Scientists have identified the elephant as a keystone species in the African savanna ecosystem. One reason is that the elephant digs holes to access groundwater that other organisms use as well. If the elephant population declined, what do you predict would happen to the ecosystem over time?

As part of the ivory trade, the African elephant was killed for its tusks. The population of African elephants decreased from 26 million in the 1800s to just 415,000 today. What component would you need to add to the model to represent the interaction that caused the elephant population to change?
